Requirements: Dimensions and configuration: See figures 1 and 2. Material: Guide pins, type X guide sockets, jackscrews and jack sockets shall be made of corrosion resisting stainless steel in accordance with ASTM A581 or ASTM A582 passivated in accordance with SAE-AMS-QQ-P-35 or shall be corrosion resistant copper nickel alloy (61 ±2% nickel, 2.5% max. other, and the balance zinc and shall have a brinell hardness of 145 to 175. Type Y guide sockets shall be beryllium copper in accordance with ASTM B196 or ASTM B197, nickel plated in accordance with SAE-AMS-QQ-N-290, class 2, 50 to 150 microinches. Plating: The contact plating shall be in accordance with MIL-DTL-55302 or gold in accordance with ASTM B488 type II, code C, class 1.27, over nickel plating in accordance with SAE-AMS-QQ-N290, class 2, 50 to 150 microinches in the engaging area and gold in accordance with ASTM B488 type II, code C, class 0.51, or type III, code A, 0.51 over nickel plating in accordance with SAE-AMS-QQ-N290, class 2, 50 to 150 microinches in the termination area and gold in accordance with. Contact identification: See figure 1. Contact engagement and separation forces (number 22 contacts): Minimum separation: 0.5 ounce. Maximum engagement: 12.0 ounces for standard force and 4.0 ounces for low force. NOTE: Low force contacts meet the requirements of standard force contacts. Mating and unmating: Standard insertion force contacts: The maximum mating force, in pounds, shall be the number of contacts multiplied by 0.56 and the withdrawal force, in pounds, shall be a minimum of 0.08 times the number of contacts and shall not exceed the measured insertion force. Low insertion force contacts: The maximum mating force, in pounds, shall be the number of contacts multiplied by 0.25 and the withdrawal force, in pounds, shall be a minimum of 0.04 times the number of contacts and shall not exceed the maximum insertion force. NOTE: Not applicable when mating and unmating is accomplished through the engaging of turning jacksets. Jackscrew and jack socket torque: 2-inch pounds maximum, fully mated. Contact resistance: The average contact resistance of all contacts measured shall not exceed 0.010 ohm, and no individual contact pair shall have a resistance exceeding 0.020 ohm. Dielectric withstanding voltage: Sea level: 1,000 volts rms. High altitude: 300 volts rms. Current rating: 5.0 amperes maximum in accordance with contact. Polarization: Type X, regular, guide pin and socket, full round (see figure 1). Type Y, adjustable D shaped guide pin and/or socket (see detail A and MIL-DTL-55302/57, detail B). All connectors are supplied in the -1 polarized position. For other than OEM use, connectors may be repolarized by using M55302/57-01 spanner wrench and M55302/63-01 guide pin and guide socket kit. When guides are removed and reinstalled in another position apply Loctite 83-CV or equivalent to the threads. Ordering connectors in other than the -1 polarized position may be done by the OEM s by placing the desired polarized position in brackets three spaces after the PIN on the purchase order. Example M55302/65-10Y [-32]. Polarization pins and sockets shall be adjusted to any desired configuration by spanner wrench (M55302/57-01). Ordering connectors in the -1 polarized position without Loctite 83-CV or equivalent applied may be done by placing a -0 in brackets three spaces after the part on the purchase order. Guide sets, as installed, shall withstand 7-inch ounces backoff torque applied through the guide set mounting nut. M55302/63-01 kit: Consists of one type Y D shaped guide socket and spanner nut and one type Y D shaped guide pin and spanner nut (see detail G). 6
